Few know blindness so profoundly as prisoners who once could see the whole world but now find the universe shrunk to the size of a cell. Inmates hear only what jailers allow, most often some version of “We own you.” As for music, the rhythm of one’s own pulse must suffice, and that hardly leads to dancing. One can even forget how to walk.

Isaiah and the Baptizer conspire to give us animal dreams in this dark season of Advent. The earlier prophet’s vision warms our hearts. Who among us hasn’t yearned for a world in which lambs could hang out with wolves and adders behave as though Mr. Rogers had taught them how to play with children? A strange political critter appears in the dream as well, one that’s not the puppet of pollsters and the powerful, but a leader with the heart and Spirit of God.
